This invention relatesrto fasteners of the button type in'which the button is secured to edto cooperate with a loop or the type adapted to cooperatewith a mating button of the snap fastener variety. More particu larly 'the invention relates to the'm'eans of forming and attaching such fasteners to material; an object oft-he invention being to provide an improved fastener construction that is exceedingly efiicient in operation and relative'ly'cheap to manufacture. V

Other objects will be apparent ,from tlie following description of aurepresentative' embodiment of the invention illustrated'in the i accompanying drawings, wherein? Figure I1 is a sectional view'of the fastener assembly attached to a piece'of fabric;

Figure 2 is a side elevation of a rivet or attaching member employed for attaching the fastener member; and

Figure 8 is a cross sectiontaken on the line 3-3 of Figure 2.

In attaching fastener assemblies to matcrial difliculties have been experienced by reason of the fastener member slippingsidewise over the material with referenceto its attaching member causing in some instances ripping of the material and in' other instances dlstortion or dlsruption of the fastener member or attaching member or-both.

According to this invention these difficulties are eliminated by providing a portion on the fastener member adapted to enter or pierce the material and hold the fastener member securely against slippage while it is being attached.

It is desirable that fastener members he i as thin as possible in order thatthey will not be conspicuous or inconvenient and will pass through laundry machines when used on washable material such as overalls. In fasteners or buttons of the snap fastener type this is often difficult; of realization because the attaching members'project so far into the fastener member as'to interfere with the proper mating of themember with its companion member unless the ,members r are made relatively deep Oltl'llClL' Accord- LEONARD a. center, OFIWAT 'T W common-e 45mm To mai e-UT ing to this invention theinteractin-g portions nee-macaw: for connecting the fastener which attachment is made, thus interfering neither withthe' lengthof the fasten'ermenn berjnorwith the-size of the head of the atta 'ch'ing member; I

Various types of attaching membe'rsf such as eyelets r1vets,'- tacks, staples and the like entrain threads of materialwith themgas niember'and attachingmembe'r are disposedsubstantially-m the plane ofthemateri'al to longitudinal edges which are suitably shape'c'l I and sufficiently. sharp to sever few strands an'd push 'back others "in passing' through the material. 7 Y, e Y

V k p In Figure 1 the rivet is shown bradded passes through the within the barrel of the fastener member.- From'this view it is seen-that theupset por 'tion lies principally ifnotentirelywithinthe barrel and does not project'into the "cupped portion of the fastenershell to interfere with the entry of a mating member. A solid tack or rivet if used would be upset within the barrel in the same manner as the llOllOWllVQt shown. The hollow rivet,'how ever,is simple and cheap to manufacture and makes a light assembly. g V v lVhile only one embodiment of the invention has been particularly illustrated and described it is to beunderstood that'vario-us changes and modifications may the made within the spirit of the invention; as set forth injthe. appended claims.
